[0027] The quantum dot film 1 includes water-oxygen barrier films on both sides and a quantum dot polymer film in the middle, and the quantum dot polymer film is fixedly connected with corresponding water-oxygen barrier films on both sides.

[0028] The working principle of the LED light guide plate brightness enhancement device based on quantum dot technology provided by the utility model is as follows:

[0029] During installation, first, quantum dot film 1 is pasted on the surface of LED light guide plate 2.

[0030] LED light guide plate 2 is bonded with right trapezoidal plate 5, and right trapezoidal plate 5 group area is placed into frame 6 and fixed frame 7 group area, and right trapezoidal plate 5 and fixed frame 7 are connected by using screws.

[0031] Example 2: This example further elaborates on Example 1. Each trapezoidal plate 5 has mounting grooves 9 at both ends, and each mounting groove 9 contains a fixed shaft 10. Each fixed shaft 10 is fixedly connected to the corresponding trapezoidal plate 5. Each fixed shaft 10 is rotatably connected to the center of a symmetrical long connecting rod 11.
